[PATCH] wifi: mt76: mt7928: makes struct beacon_tlv 4-byte aligned.

[PATCH] wifi: mt76: mt7928: makes struct beacon_tlv 4-byte aligned.

[Anthony Liu]

mt76 fails when offloading beacon to MT7928 FW.

This is caused by newly added 4-byte alignment check in MT7928 FW
and works when beacon_tlv is 4-byte aligned. MT7925 is not affected
because it accepts same struct with or without extra padding bytes.
